Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a null pointer dereference in the perf/x86/intel/pt component of the Linux kernel, which can cause a kernel crash when a PT stop filter range is hit while tracing. This is due to a missing check for the
buf->single variable before calling pt buffer region size. The problem was introduced by a commit that added support for PT single-range output mode. When execution hits a configured stop filter, the kernel will crash because of the null pointer dereference in pt handle status due to calling pt buffer region size without a ToPA configured.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
